CHARLES I1. TAYLQR, OF SAN FRANCISCO, CALIFORNIA.

CHECKREIN-LOCK.

Specification of Letters Patent.

Patented Dec. 3%, 1913.

Application filed February 16, 1912. Serial No. 677,982.

To all whom it may concern:

Be it known that I, CHARLES L. TAYLOR, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Checkrein-Locks, of which the following is a specification.

This invention relates to check rein locks and the object of theinvention is to provide a simple and eflicient device of this characterwhich may be readily operated so that the horses head may be released topermit him to drink or graze and may then be checked up without causingthe driver to descend from his seat.

Further objects of this invention will appear as the following specificdescription is read in connect-ion with the accompanying drawing, whichforms a part of this application, and in which Figure 1 is a sideelevation of the check rein terret. Fig. 2 is an edge elevation of thesame applied to the strap with the pawl in the position to hold thestrap in its adjusted position. Fig. 3 is a similar View with the pawlarranged to ride idly over the rack bar so that the horse can readilylower his head.

Referring more particularly to the drawing, the terret is provided witha threaded stem 1 having a nut 2 thereon for connecting the head 3 tothe saddle. The head 3 comprises an open-Work frame having a transverseslot 4: extending therethrough and adapted to receive the check reinstrap 5. The end a of the strap is adapted to be connected to theordinary head piece of a check rein and-the opposite end 6 .is adaptedto extend beyond the saddle a sufficient distance to be then reached bythe driver. At a suitable point upon the strap, there is secured araised rack bar 6 preferably in the form of a corrugated sheet of metal,Whose Gopies of this patent may be obtained for five cents each, byaddressing the Commissioner upper edge is raised above the top wall ofthe slot which passes between the connecting legs of the head, as shown.

Pivo-tally connected between the legs of the head is a freely rotatablepawl 7 whose lower end is substantially flush with the upper wall of theslot when in vertical position and which is adapted to engage the rackbar on either side of the head, as shown in Figs. 2 and 3.

When the pawl is extended to the right side of the head, the horse cannot pull the check rein out of the terret but by pulling the straptoward the rigat, or more correctly speaking, toward the driver untilthe pawl drops off the rack, it will be readily seen that the strap maymove in the opposite direction or toward the horses head, thuspermitting the horse to lower his head for drinking or grazing. Afterthe. pawl has passed the opposite end of the strap and the driver pullsupon the strap to check up the horse, the pawl will extend from the headin a proper direction to engage the rack bar for preventing the animalfrom becoming unchecked.

What is claimed is A check strap lock comprising a guiding terret for astrap, a rack bar arranged to be carried by the strap, and a pendulumpawl freely and pivotally mounted in the terret and having a lengthbetween its pivot and its lower end greater than the distance betweenthe pivot and the upper surface of the rack bar when in operativeposition beneath the terret and less than the distance between the pivotand the lower surface of said rack bar.

In testimony whereof I affix my signature in presence of two witnesses.
